CTC: the technology for protection at a higher level! CITEL, the experts in surge protection, take the protection of your photovoltaic installation to a whole new level! With the innovative CTC technology, your PV installation will be protected even more effectively and reliably against damage caused by surges. The innovative and patented CTC-Technology (Central Thermal Control) is an entirely new designed disconnection technology. It is safer, faster, and more compact than previous disconnections. Its cutting-edge technology has been rewarded with numerous patents for CITEL. It counters the weaknesses of previous disconnection devices primarily through: Its thermo-sensitive solo separation point, which is spatially centrally placed in the SPD The additional insulating safety barrier integrated into the isolating device for more reliable separation of the poles in the event of separation. This game-changing technology brings a number of benefits for you: Space saving due to more compact design Short conductor lengths between MOV and cut-off device Fast triggering of the cut-off by cumulative heat impact of all MOVs on one heat point Additional insulation barrier for even safer pole separation All-pole disconnection in case of tripping No risk of varistor short circuits Much lower temperature of the SPD envelope during disconnection providing more safety For the user or side by side electrical devices C T C "CENTRAL“ - The central position of the disconnection device "THERMAL“ – More efficient use of Joule-heat for more safety "CONTROL“ – All-pole disconnection with dual mechanism Upload flyer CTC-Technology
